APPARATUS rue GRAIN, on: THE LIKE.

To czll'whom may concern:

B'e' it known tlratTfFAwcEr'r H: Corrrrrs, a citizen of Gitfitt Bl'ltalll, residing-at Denver, in the countyof Denver and State-(if Colorado, "have invented certain new and useful lmproveineiits in Apparatus for Lifting WaterjGrain, or the like,-of which the following is a specification, 'refere'nce being had to the accompanyingdrawings.

My invention relates *to elevating apparatus involving the use of "centrifugal force.

An object of this'inv'ention'istoprovide an apparatus involving a pl-urality of outwardly slanting Open-ended condiiitshaving a rotary movement about a vertical axis around which they are eqiridistantly 'a'i' 'lziliged.

A'fu'rther object of this iliVGDliil'Oll i-sto provide in an "apparatus fof the above described "character certain flIlPlOVlTlQfliiS in the con struction andamingement of its p arts which by utilizing the 'ii iertia of liquid to -be lifted andftaperin "O1- attenuation era column of liquid,' attain to a manual-in capacit'y with they expenditure "of *min-inium motive energy andspeed.

.A further object (if this invention is to combine in "a single means the "advantages severally attainable. viz. to utilize the inertia of the liquid to be lifted to initiate the lifting movement mid to establish tapering or attenuation of an inclined column of liquid in an elevating conduit as contra-distinguished to a column of liquid filling the en tire conduit.

My invention consists in the construction, arrangement and con'lbinat-ion of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which- Figure 1 is a. vertical sectional View of one form of my apparatus. Figure 2 is a top plan view of the same. Figure 3 1s a detail sectional View of one of the conduits.

In the construction of the apparatus as shown, the numeral designates a supporting frame, of any suitable form, extending to any desired height and at its lower end entering a body of water. The lower end of the supporting frame 10 is provided with a base 11 and a vertical shaft 12 is stepped on said base by ballbearings 13, having a protective cover 1 carried by a sleeve 15.

Mounted on the shaft 12 are collars 16, 17 and atta'ched to these collars are outwardly extending-arms,'18. The uppermost arms 18 are of greater length than the lower mostarms: an'd conduits or pipes 10, in this instance four in number, are mounted in and supported bysaidarms. The conduits or pipes 19 are inclined radially of the verticalshaft 12and preferably are located equidistant "therefrom. 'Ihe lower end portion'ofwach conduit o'r pipe .19 is i'fonmed with an inlet opening :20 (if-substantially the same"diameter as the conduit, the inlet opei'iings of all of the pipes Opening inithe direction of travel or rotary moreme-ut thereof.

The centers of' the inlet op'enings 20: are in 't-he axial planes of the conduit an'cl fall in a common circle concentric with the axis cf the shaft- 12. The upper end of each conduitor pipe 19 is closed by a reaiavardly curved surface andalso 'is forn'ied with an outlet opening '21 disposed reversely nvith relation to-the opening 0. 'I h-at is'to say, the outletopenings 21 of the several conduits 19 open rearwardly relative to the rotary inotion or direction of travel of the several cond-uits. lhe centers of theoutlet openings 21 :a1"e in the axial. planes of the condu its andfall' within a circle "concentric with the axis of the shat-t1? ot'larger diameter than the circle 'relativeto the intake opeuings 20. The upper end portion of the frame 10 supports the upper end of the shaft 12 in an anti-friction bearing 22, carrying a pulley 23 whereby power may be applied from any suitable source to rotate the shaft 12 at high speed in the direction of the arrow indicated. Extending around the upper ends of the elevating conduits or pipes 19 and disposed slightly below the horizontal plane of the outlet openings thereof, is an annular trough 24 having a discharge chute 25 ext-ending tangentially therefrom, a separating wall 26 forming the inner wall of the discharge chute and extending in a direction concentric to the center of the trough. I

When the element consisting of the shaft 12, arms 18 and conduits 19, is rotated in the direction of the arrow in Figure 2, the movement of the lower ends of the conduits beneath the level of the liquid in the source of supply causes the liquid to enter through conduit into the trough 2i, partly by centrifugal force, partly by the tendency of the liquid to continue to move in a straight line and partly by the tendency ofthe liquid to fall and come to rest at the outlet openings of the conduits.

In upward and radial travel in each conduit the column of liquid becomes tapered or attenuated and flattened out into segmental form in cross-section on the rear walls of the conduits so that it does not fill or fully conform to the cross-section of any conduit, and is discharged by the outlet openings 21 into the trough.

This apparatus does not require priming. hen rotated the conduits will engage the liquid or other matter and raise it to the de sired extent and discharge it intothe trough under two major conditions, viz, the radial inclination of the conduits and the velocity or rotary speed thereof, modified by two minor conditions, viz, the forwardly opening uniform inlet ports having their centers in the axial planes of the conduits, and the rearwardly opening outlet ports of uniform diameter having their centers in the axial planes of the conduits.

I claim 1. An elevating machine of the character described comprising an element mounted for rotation about a vertical axis and includ' ing a plurality oii continuously straigh t conduits slanting upwardly and outwardly from said axis, each conduit having at its lower end an intake opening having its center in the axial plane of the conduit and facing in the direction of rotation of the element and at its opposite end a discharge opening having its center in the axial plane of the conduit and disposed in the circle of rotation of said end and rearwardly of the same with relation to the direction of rotation.

2. An elevating machine of the character described comprising an element mounted for rotation about a vertical axis and including a plurality of nonangular conduits slanting outwardly from said axis, each conduit having at its lower end an intake opening having its center in the axial plane of the conduit and facing in the direction of rotation of the element and at its opposite end a discharge opening having its centerin the axial plane of the conduit and disposed in the circle of rotation of said end and rearward of the samewith relation to the direction of rotation.

3. An elevating machine of the class described, comprising an element mounted for rotation about a vertical axis and including a plurality of straight conduits and slanting upwardly and outwardly from said axis, each conduit having at its lower end an intake opening having its center in the axial plane of the conduit and facing in the direction of rotation of the element, and at its upper end a discharge opening having its center in the axial plane of the conduit and in the circle of rotation of said end and rearwardly of the same with relation to di' rection of rotation, said straight tubes having end walls and presenting interior concave surfaces opposite said openings.

In testimony whereof I hereunto al'lix my signature.
